Benign Pankreas Hastalıklarının Tanısında Endoskopik Yöntemler
Özet
Benign pankreas hastalıkları, organın retroperitoneal yerleşimi ve karmaşık anatomik komşulukları nedeniyle klinik ve radyolojik olarak tanısı güç lezyonlar arasında yer almaktadır. Bu hastalıkların yönetiminde Endoskopik Ultrasonografi (EUS) ve Endoskopik Retrograd Kolanjiopankreatografi (ERCP) en sık kullanılan iki temel yöntemdir. Yüksek çözünürlüklü görüntüleme sunan EUS; idiyopatik akut pankreatit etiyolojisinin saptanmasında, konjenital anomalilerde ve parankimal değişikliklerin izlendiği erken evre kronik pankreatit tanısında güvenli bir ilk basamak aracıdır. Pankreas parankimini değerlendiremeyen daha invaziv bir yöntem olan ERCP ise yüksek post-ERCP pankreatit riski nedeniyle günümüzde tanısal amaçlardan ziyade terapötik işlemlere ayrılmıştır. ERCP; kronik pankreatite bağlı kanal darlıkları, koledok taşları, safra çamuru, kanal kaçakları ve Oddi sfinkter disfonksiyonunun sfinkterotomi ve stentleme ile tedavisinde başarıyla uygulanmaktadır. Sonuç olarak, gelişen endoskopik teknolojiler benign pankreas süreçlerinde tanı doğruluğunu artırırken tedavi süreçlerini optimize etmektedir.
Benign pancreatic diseases present significant diagnostic challenges due to the organ's retroperitoneal localization and intricate vascular and anatomical relationships. Endoscopic Ultrasonography (EUS) and Endoscopic Retrograde Cholangiopancreatography (ERCP) constitute the primary endoscopic modalities utilized in their clinical management. EUS provides detailed, high-resolution evaluation of the pancreatic parenchyma and ductal structures, rendering it the preferred non-invasive approach for investigating idiopathic acute pancreatitis, congenital anomalies, and early-stage chronic pancreatitis. In contrast, ERCP is a highly invasive procedure with an associated risk of post-procedural pancreatitis, which has restricted its contemporary role predominantly to therapeutic interventions rather than diagnostic mapping. ERCP remains highly effective in managing ductal pathologies, including choledocholithiasis, biliary sludge, pancreatic duct strictures, leakages, and Sphincter of Oddi dysfunction, through sphincterotomy and stent placement. Consequently, ongoing technological advancements in these endoscopic methods significantly enhance diagnostic precision and optimize therapeutic outcomes.
